In this work, a continuous hybrid approach (CHA) to the modified resonant frequency calculation for circular microstrip antennas with and without air gaps is presented. The results obtained by the CHA for different antenna dimensions and modes of resonance are compared with the experimental and theoretical results given in the literature. © 2004 Wiley Periodicals, Inc.

The genetic‐based approach to the modified resonant frequency calculation for E‐shaped and H‐shaped microstrip patch antennas is presented.Continuous parameter genetic algorithm (CPGA) has been used to modify the resonant frequency expressions of E‐shaped and H‐shaped microstrip antennas. The results obtained by CPGA for different antenna dimensions are compared with the experimental and theoretical results given in the literature. © 2011 Wiley Periodicals, Inc.
